Anatomical Terminology

La terminología anatómica estándar se usa universalmente para estudiar la estructura y la organización interna del cuerpo humano.
Estos términos a menudo tienen raíces, prefijos o sufijos derivados del griego o del latín. La raíz es la parte central de la palabra que puede referirse a un órgano, tejido o afección. 
Por ejemplo, la raíz gastro se refiere al estómago. Al agregar epi, que significa arriba, como prefijo antes de la raíz se crea el término epigástrico, que describe la ubicación por encima del estómago.
El sufijo que es se refiere a la inflamación. Al vincularlo a la raíz artro-, que significa articulaciones, se forma el término artritis. Del mismo modo, la bronquitis y la gastritis significan inflamación de una parte de los pulmones y el estómago, respectivamente.
Del mismo modo, para comprender las direcciones anatómicas, los anatomistas utilizan la posición anatómica de referencia estándar. Por ejemplo, cuando una persona está de pie mirando hacia adelante, la parte delantera del cuerpo se llama lado anterior o ventral, y la espalda es el lado posterior o dorsal.
Así, el corazón es anterior a la columna vertebral y posterior al esternón.

terminología anatómica

El conocimiento de anatomía es esencial para comprender la biología humana y la medicina. Los anatomistas y los profesionales de la salud utilizan una terminología estándar para describir el cuerpo humano con mayor precisión y sin ambigüedad. Los términos anatómicos tienen raíces principalmente griegas y latinas. Debido a que estos idiomas rara vez se utilizan en conversaciones, el significado de las palabras sigue siendo el mismo. Cada término se compone de una raíz entre los prefijos y sufijos. La raíz de un término a menudo se refiere a un órgano, tejido o condición, mientras que el prefijo o sufijo describe la raíz. Por ejemplo, en el trastorno de la hipertensión, el prefijo "hiper-" significa "alto" o "sobre" y la palabra raíz "tensión" se refiere a la presión, por lo que la palabra "hipertensión" se refiere a una presión arterial anormalmente alta.

Los anatomistas han estandarizado la manera en que se observa el cuerpo. La posición de referencia anatómica estándar es estar de pie con los pies paralelos, los hombros anchos y los dedos de los pies hacia adelante. Los miembros superiores se mantienen a cada lado y las palmas de las manos miran hacia adelante. Siguiendo la posición de referencia anatómica estándar para localizar o referirse a la parte del cuerpo se minimiza la confusión, especialmente durante exámenes y procedimientos de rutina. Por ejemplo, una cicatriz en la parte carpal está en el lado palmar de la muñeca. En cuanto a la orientación, el cuerpo acostado se describe como estar en posición prona (cara abajo) o supina (cara arriba).

Además, las regiones del cuerpo humano tienen términos específicos para indicar la ubicación, número o color de una estructura, órgano o tejido en particular. Por ejemplo, el término "brachium" se refiere al "brazo superior" y se utiliza "antebrachium" o "antebrazo" en lugar de "brazo inferior". Los términos se vuelven esenciales al describir las ubicaciones relativas de diferentes estructuras corporales. Por ejemplo, los términos superior e inferior se utilizan a menudo para describir la posición de la cabeza con respecto a la parte inferior del cuerpo.

Breve historia

Terminología Anatómica (TA) es el estándar internacional de terminología anatómica utilizada en todo el mundo. El Comité Federativo de Terminología Anatómica y la Federación Internacional de Asociaciones de Anatomistas la desarrollaron y lanzaron en 1998. Reemplazó el estándar anterior Nomina Anatómica. Terminología Histológica (TH) es un texto complementario de TA desarrollado por el renombrado Comité Internacional Federativo de Terminología Anatómica (FICAT) que se publicó en 2008. TA contiene terminología para aproximadamente 7500 estructuras anatómicas humanas (macroscópicas), mientras que TH contiene terminología para estructuras celulares, tejidos y órganos a nivel microscópico.

KEY TERMS AND CONCEPTS

TÉRMINOS Y CONCEPTOS CLAVE

anatomical terms and body position

Anatomical terms help describe the human body clearly in biology and medicine. Health care professionals and anatomists use this standard language to avoid confusion and to make descriptions more precise. Most anatomical words come from Greek and Latin roots, and these roots usually stay the same because the languages are rarely used in everyday conversation.

Many anatomical words are built from a root plus a prefix or suffix. The root often names an organ, tissue, or condition. The prefix or suffix then changes the meaning of that root. For example, in hypertension, the prefix &quot;hyper-&quot; means high or over, and the root &quot;tension&quot; refers to pressure. Together, the word means abnormally high blood pressure.

Anatomists also use a standard anatomical reference position to describe the body. In this position, a person stands upright with parallel feet, shoulders wide, toes forward, and the arms at the sides. The palms face ahead. Using this common position helps people locate body parts with less confusion during exams and procedures.

Orientation terms also matter when describing body position. A body lying face down is called prone, and a body lying face up is called supine. Location terms are used for specific regions as well. For example, brachium means upper arm, and antebrachium means forearm rather than lower arm. A scar on the carpal is on the palm side of the wrist, and terms such as superior and inferior help compare the head with the lower part of the body.

These terms are part of international standards used worldwide. Terminologia Anatomica, or TA, was developed by the Federative Committee on Anatomical Terminology and the International Federation of Associations of Anatomists and released in 1998. It replaced Nomina Anatomica. A related reference, Terminologia Histologica, or TH, was published in 2008 by the renamed Federative International Committee on Anatomical Terminology. TA covers about 7,500 gross anatomical structures, while TH covers cellular structures, tissue, and organs at the microscopic level.

How Anatomy and Physiology Work Together

Human anatomy studies the structures of the body. Some body structures are so small that they can only be seen and examined with a microscope. Others are large enough to be viewed, handled, measured, and weighed. The word anatomy comes from a Greek root meaning “to cut apart.” Early study of the human body began with observing the outside of the body and the injuries seen in soldiers and other patients. Later, physicians were allowed to dissect dead bodies to learn more. Dissection means...

Levels of Organization in the Human Body

The human body is organized in levels that build from simple parts to a complete living being. These levels increase in complexity from subatomic particles, atoms, and molecules to organelles, cells, tissues, organs, organ systems, and the organism. At the chemical level, scientists study the smallest building blocks of matter. Matter is made of elements, which are pure substances such as hydrogen, oxygen, carbon, nitrogen, calcium, and iron. The smallest unit of an element is an atom, and...

How the Human Body Keeps Going

Human life depends on metabolism, movement, development, growth, and reproduction. These functions help the body stay alive, maintain itself, and continue the species. Together, they show how the body uses energy and changes over time. Metabolism is the body’s use of energy and food molecules. It helps the body make fuel for movement, support body functions, and build and maintain body structures. Metabolism includes two kinds of reactions: anabolism and catabolism. Anabolism is the process...

Human Survival Needs in the Body

Human survival depends on air, water, food, a narrow temperature range, and a narrow range of atmospheric pressure. The Earth and its atmosphere provide these conditions, but the body can only function well when they stay within limits. Oxygen is one of the most important needs. Atmospheric air is only about 20 percent oxygen, but that oxygen supports the chemical reactions that keep the body alive, including the reactions that make ATP. Brain cells are especially sensitive to a lack of oxygen...

what is homeostasis?

Homeostasis and Negative Feedback

Homeostasis keeps the body’s internal conditions stable. The body does this by holding each physiological condition near a set point. A set point is the value around which the normal range changes, and the normal range is the small group of values that is healthiest and most stable. Human body temperature is a common example. Its set point is about 37°C, or 98.6°F, and it can shift a little above or below that point while still staying in range. Negative feedback helps maintain homeostasis.

negative and positive feedback

Feedback Loops in Body Balance

Negative and positive feedback help keep body conditions stable. These feedback loops control many body processes and support homeostasis, which is the maintenance of a steady internal environment. Negative feedback reduces a change and brings a system back toward its normal state. Positive feedback increases a change and pushes a process further in the same direction. Together, they show how the body can fine-tune responses when conditions shift. These control systems are important in many...

homeostatic imbalance

How Feedback Failure Disrupts Homeostasis

Homeostasis keeps the body’s internal conditions stable so cells, tissues, organs, and organ systems can work properly. The body uses control systems to regulate temperature, blood pressure, pH balance, and fluid balance. These controls depend on feedback loops, which can be positive or negative. Homeostatic imbalance happens when those feedback loops fail and the body can no longer maintain a stable internal environment. Injury, disease, environmental changes, genetic mutations, and aging can...

anatomical positions

Body Positions Used in Anatomy

Body positions used in anatomy give a shared way to describe where body parts are and how they face. These standard references help people talk about anatomical structures with the same meaning. The anatomical position is the main reference point for body orientation. In anatomical position, the body stands upright and faces forward. The feet are parallel and flat on the floor. The arms rest at the sides with the palms facing forward, and the head and eyes point forward. The most common...

regional terms

Anatomy Regions and Body Landmark Terms

Anatomy regions and body landmark terms help identify specific parts of the human body. These regional terms divide the body into areas with structures that support similar functions. They also make it easier to describe the exact area affected by an injury or disease. The human body is organized into two major regions: the axial region and the appendicular region. The axial region includes the body from the head to the abdomen and forms the central body axis. The appendicular region includes...

directional terms

Anatomical Direction and Body Position

Anatomical direction and body position terms help describe where one body structure is located in relation to another. These terms use comparisons, such as one tissue being inferior to another or a tumor being superficial to a deeper structure. They are based on the standard anatomical reference position, which uses the body in an upright pose. Anterior and posterior are a common pair of directional terms. Anterior, also called ventral, means toward the front of the body. Posterior, also...

body planes

Anatomy Sections and Body Planes

Anatomy sections and body planes are imaginary flat surfaces used to divide the body for study. They help show the orientation, relationships, and spatial layout of anatomical structures. These reference planes are also useful for describing organs and body parts in a standard way. The sagittal plane divides the body or an organ vertically into right and left sides. When that cut goes through the middle and makes equal halves, it is called the midsagittal or median plane. When it makes unequal...

anatomical movements

Body Joint Motion Terms

Body joint motion terms describe how bones and muscles move at different joints. These standard names make it easier to talk about range of motion in the body. They are used to describe actions at the shoulder, hip, elbow, knee, wrist, fingers, toes, and spine. Flexion and extension are movements in the sagittal plane, also called the anterior-posterior plane. Flexion is the forward bending motion of the head or vertebral column. Extension is the backward movement or straightening of a joint,...

abdominal regions and quadrants

Abdominal Pain and Organ Location

The abdominal cavity is divided into quadrants and regions to help locate organs and describe pain clearly. Clinicians and anatomists use imaginary lines to mark the abdominopelvic cavity. This system makes it easier to communicate about a patient’s symptoms or a suspicious mass. The simpler method divides the area into four quadrants. One horizontal line and one vertical line cross at the umbilicus, or navel. These quadrants are the right upper quadrant, right lower quadrant, left upper...
